The invention relates to a load hoisting method of an electric hoisting system, a load hoisting device of the electric hoisting system, a storage medium and the electric hoisting system. The load hoisting method of the electric hoisting system comprises the steps that when the electric hoisting system hoists a to-be-hoisted load, the winch phase current of the winch and the oil pump phase current of the hydraulic oil pump motor are monitored when the to-be-hoisted load is hoisted. The first weight of the to-be-hoisted load is determined through the winch phase current, the second weight of the to-be-hoisted load is determined through the oil pump phase current, and whether the to-be-hoisted load is overloaded or not is comprehensively judged by combining the first weight and the second weight. And finally, hoisting operation corresponding to the determined result is executed according to the determined result. Therefore, the hoisting condition under the overload condition of the to-be-hoisted load can be effectively reduced, and the hoisting safety is improved.
本公开是关于一种电动吊装系统的负载吊装方法、电动吊装系统的负载吊装装置、存储介质及电动吊装系统。该电动吊装系统的负载吊装方法,包括:电动吊装系统对待吊装负载进行吊装时,监测对待吊装负载进行吊装时卷扬机的卷扬机相电流及液压油泵电机的油泵机相电流。通过卷扬机相电流确定出待吊装负载的第一重量、通过油泵机相电流确定出待吊装负载的第二重量,通过结合第一重量和第二重量来综合判断待吊装负载是否超载。最后根据确定结果执行与确定结果对应的吊装操作。如此可有效减少待吊装负载超载情况下起吊的情况,提高吊装安全性。
